Thanks, new guy Paul, who lives a mere 2 hours away in Buffalo, and welcome to this group of balmy persons. 
I have only the one LXI with the wheels and opening to the side cordwinder. Most probably passed on it on ebay but if you looked close you could just make out the axle, so I went for it 3 weeks ago. It's the one I drove to Port Huron to pick up in person. That completes the LX series group for me. See thread #2157 url.
